From a65da4859191d8e974211e03ef9223a3bd6c68d1 Mon Sep 17 00:00:00 2001 From: martmull Date: Wed, 22 Jul 2026 19:28:17 +0200 Subject: [PATCH] feat(server): per-worker queue filtering via env vars (#23181) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Context Follow-up to #23134. Goal: stop a heavy/long-running queue from saturating every worker pod and blocking the whole job pipeline, by letting each BullMQ worker decide **which queues it consumes** from env vars. > Note: an earlier revision of this PR also added a dedicated `application-queue` (concurrency 1). Per review, that was dropped — application install/upgrade/backfill jobs stay on `workspaceQueue`. This PR now contains **only** the worker queue-filtering mechanism. ## What changed - The queue-worker explorer (`MessageQueueExplorer`, which only runs in the `queue-worker` process) now reads two env vars before creating workers: - `WORKER_ENABLED_QUEUES` — comma-separated allowlist of queues this worker processes (empty = all). - `WORKER_EXCLUDED_QUEUES` — comma-separated denylist, applied after the allowlist. - Workers are only created for queues that pass the filter; filtered-out queues are logged and skipped. Unknown queue names are logged as warnings. - Both vars are read directly from `process.env` (not the DB-backed config-variable system), since they're worker-bootstrap settings. - Pure decision logic + env parsing extracted to `shouldCreateWorkerForQueue` / `parseQueueListFromEnv` utils with unit tests. Queue **clients** are still registered in every process, so jobs can be enqueued from anywhere — only the **consumer** side is gated. ## Usage Isolate `workspace-queue` (where the application jobs run) onto dedicated pods: - General worker pods: `WORKER_EXCLUDED_QUEUES=workspace-queue` - Dedicated worker pods: `WORKER_ENABLED_QUEUES=workspace-queue` ## Tests - `should-create-worker-for-queue.util.spec.ts`: allowlist / denylist / precedence + env parsing. - `typecheck` + `oxlint --type-aware` + `oxfmt --check` clean on the diff. ## Companion - twentyhq/twenty-infra#805 wires `WORKER_ENABLED_QUEUES` / `WORKER_EXCLUDED_QUEUES` to the worker pods. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_014XeN6wVSbMWnFu8jeLaSXk --------- Co-authored-by: Claude Fable 5 --- .../message-queue/message-queue.explorer.ts | 56 ++++++++++++++-- ...hould-create-worker-for-queue.util.spec.ts | 65 +++++++++++++++++++ .../should-create-worker-for-queue.util.ts | 17 +++++ .../twenty-config/config-variables.ts | 20 ++++++ 4 files changed, 153 insertions(+), 5 deletions(-) create mode 100644 packages/twenty-server/src/engine/core-modules/message-queue/utils/__tests__/should-create-worker-for-queue.util.spec.ts create mode 100644 packages/twenty-server/src/engine/core-modules/message-queue/utils/should-create-worker-for-queue.util.ts diff --git a/packages/twenty-server/src/engine/core-modules/message-queue/message-queue.explorer.ts b/packages/twenty-server/src/engine/core-modules/message-queue/message-queue.explorer.ts index d6bf9eb222..6030ccf8e6 100644 --- a/packages/twenty-server/src/engine/core-modules/message-queue/message-queue.explorer.ts +++ b/packages/twenty-server/src/engine/core-modules/message-queue/message-queue.explorer.ts @@ -18,9 +18,11 @@ import { type MessageQueueWorkerOptions } from 'src/engine/core-modules/message- import { ExceptionHandlerService } from 'src/engine/core-modules/exception-handler/exception-handler.service';
